Writes passwords.dex.coreos.com CRs against the in-cluster Kubernetes
API using the pod's service-account token + cluster CA (no kubectl /
client-go dependency). NewPasswordClient returns ErrNotInCluster off
cluster so the web layer degrades gracefully in dev.
Load-bearing: Dex's kubernetes storage types Password.Hash as []byte,
which k8s JSON-marshals as base64 — so the `hash` field carries the
base64 of the bcrypt string, not the raw string. Storing the raw string
makes Dex's base64-decode-on-login produce garbage and every login fail.
409 -> ErrPasswordExists, 401/403 -> ErrForbidden (RBAC missing) so the
handler can give precise messages. Tested against an httptest TLS server.
bcrypt cost-12 hashing lives in the web handler; golang.org/x/crypto was
already a transitive dep (now promoted in go.sum).

Stage-1 email onboarding: Mathias mints an invite, the recipient claims
it to set a Dex password. Invitations exist before their user, so the
table carries no user_id FK and is deliberately outside RLS — the
32-byte crypto-random token is the capability (single-use, time-boxed).
ClaimInvitation consumes atomically (UPDATE ... WHERE used_at IS NULL
... RETURNING) so concurrent claims of one token can't both succeed.
PeekInvitation validates the link for the form without consuming it.

Small tapir slice to make the gate measurable as written: append-only
login_events (RLS, per-user-per-day throttle) + a union query over reads
(login_events) and acts (summary_actions) for distinct-active-weeks. Carries the
honesty caveats (unprompted not measurable; data accrues from deploy; week-bucket
noise at low N) and the delete-cascade footgun (no FK, needs explicit delete +
test) from the prior delete work. Out of scope: analytics, prompt-tracking,
dashboards.
Reframes "unprompted" from an enforced criterion to a named measurement
limitation: organic-vs-prompted returns aren't distinguishable from any data
Tapir holds, so in practice all returns are counted and the result read with that
caveat (a nudged return is a weaker signal). Adds a "how it's measured" note
pointing at summary_actions (acts) + a new append-only login-events table
(read-returns), which accrue from deploy onward. Honest about the gap rather than
silently dropping the word.
A discovered-but-unsummarized video whose caption fetch was rate-limited now
shows a passive ⏳ "Retrying later" chip (dim CharmDim styling, not the accent)
instead of the Summarize button — the user cannot fix a 429, the runner retries
automatically once the backoff window expires. Regenerated views_templ.go.
Co-Authored-By: Claude Opus 4.8 (1M context) <noreply@anthropic.com>
After ProcessNewVideo the runner records transcript_status per outcome:
rate_limited (stamps the backoff clock), none, or fetched. Before fetching, a
video inside the TAPIR_FETCH_BACKOFF window is skipped (SkippedRateLimited) so a
just-429'd caption endpoint is not re-hit; once the window expires it retries.
Backoff/clock injected via variadic Options (WithBackoff, WithClock) so existing
New call sites and the fake-driven loop tests stay valid. Backoff 0 = always retry.
Co-Authored-By: Claude Opus 4.8 (1M context) <noreply@anthropic.com>
Adds FetchBackoff (Go duration, default 1h) controlling how long the run loop
waits before re-fetching a transcript that returned HTTP 429. Zero means always
retry. Not required by ValidateForRun — a zero/unset value is a valid policy.
Co-Authored-By: Claude Opus 4.8 (1M context) <noreply@anthropic.com>
The engine already distinguishes SourceNone from SourceRateLimited internally
but collapsed both into Skipped. Expose the source string so the runner can
persist the right transcript_status and apply rate-limit backoff, without the
engine taking on any store/retry concern (dependencies still point inward).
Co-Authored-By: Claude Opus 4.8 (1M context) <noreply@anthropic.com>
Surfaces videos.transcript_status (migration 007) on SummaryRow and adds
SetTranscriptStatus / GetTranscriptStatus / RateLimitedVideoIDs.
SetTranscriptStatus is the single choke point for the rate-limit lifecycle:
"rate_limited" stamps rate_limited_at = NOW(), every other status clears it,
so the runner's backoff window and the UI badge read one consistent source.
RateLimitedVideoIDs is the per-pass loader (mirrors SeenVideoIDs) the runner
uses to skip still-throttled videos without re-hitting the caption endpoint.

Logout was only reachable from /welcome. Users who are logged in had no way
to sign out from any app page (list, detail, account). Added to the shared
nav alongside Account.
Records the gate change: Stage 0 now passes when either the maintainer or an
onboarded friend returns unprompted in >=2 separate weeks. Behavioural (return
usage), not feedback-based, to resist politeness bias. Includes an honest
self-scrutiny note that this is a guardrail edit made while the original gate was
unmet — examined on that basis and proceeding because it broadens who supplies the
signal without softening the kind of signal required. Adds feedback-based-gate to
rejected alternatives.
Adds videos.transcript_status (NULL|none|fetched|rate_limited) and
videos.rate_limited_at, so the runner can record a 429 and skip re-fetching a
still-throttled video until a backoff window elapses. Columns inherit the
existing videos RLS policy (migration 003); no policy change needed.
Co-Authored-By: Claude Opus 4.8 (1M context) <noreply@anthropic.com>
The baseUrl fetch mapped every non-200 to SourceNone, recording a 429 as a
permanent "no captions". 429 is the IP being rate-limited, not an absent
transcript. Return SourceRateLimited (still a graceful degrade, no error) so
the runner can retry after a backoff window. Other non-200s (403/404/5xx)
stay SourceNone.
Co-Authored-By: Claude Opus 4.8 (1M context) <noreply@anthropic.com>
Videos rows are created by `tapir run`, not when a YouTube account is
connected, so a freshly-connected account correctly shows an empty list —
but the old empty state ("No videos yet") gave no clue why or what to do.
Split it on whether the user has any connection:
- connected, no videos: a distinct accent callout telling them to run
`tapir run` to discover subscriptions.
- not connected: a prompt with a Connect YouTube button.
handleList fetches connections only when the list is empty. Includes
web-shot captures of all three states under docs/ux-review/fixes/.
Co-Authored-By: Claude Opus 4.8 (1M context) <noreply@anthropic.com>
429 from the caption endpoint means the IP is rate-limited (retry later),
not that the video has no captions. Distinguishing it from SourceNone is the
prerequisite for the runner's backoff/retry logic.

The "Get Started" button drops users straight into the shared Dex flow,
which has no separate "register" option — registration completes
automatically after first login. Users new to Tapir had no signal that
signing in is also how they sign up. Reword the sub-text to say so
explicitly, keeping the single Dex CTA (sign-in and sign-up are one flow).
Co-Authored-By: Claude Opus 4.8 (1M context) <noreply@anthropic.com>
The .btn class sets color:var(--accent-fg), but the generic a{} and
a:visited{} rules outrank it on <a> elements, so anchor buttons (the
landing "Get Started" CTA, "Connect YouTube") rendered their label
accent-on-accent — invisible. Add a.btn / a.btn:visited to restore the
button foreground.

Replaces the original "useful to me, specifically" gate with "me OR a friend
returns unprompted in >=2 separate weeks" — friendly-user signal counts, but the
test stays behavioural (return usage) not feedback-based, to resist politeness
bias. Folds the old Stage 1 ("a trusted user returns") into the new Stage 0 (they
were near-identical), renumbers hardening to Stage 1, and updates the drift
signals (the gate can be softened by mistaking polite feedback for evidence;
multi-user shipping ahead of the gate was a recorded exception per ADR-012, not a
precedent). Rationale recorded in ADR-016.
Records the infra#88 spike decision: per-user OAuth tokens are runtime app-state,
not config, so they live envelope-encrypted in PG18 under RLS (key from 1P via the
existing read-only SA) rather than in the vault. Infra creds stay ESO/1Password —
two mechanisms because they're two different things. Includes the falsification
conditions (frequent rotation; estate audit policy; key-rotation cost) so the
choice is earned not assumed. Adds the two rejected candidates (vault-write SA;
Supabase) to the rejected-alternatives table. Full reasoning in the #88 decision
doc; build + reboot-validation in #89.
Mirror to github.com was failing with 'unsupported in libcrypto' on every run
(OpenSSL 3.6 / OpenSSH 10 dropped support for the existing key format). Removed
rather than leave it polluting the CI signal. Re-add when the deploy key is
rotated to ed25519.
The Stage-0 ui-spec (ADR-011) predated multi-user and several UX
features. Appended a "Deviations and additions (as-built)" table —
without rewriting the spec — recording each feature shipped beyond it
(multi-user+RLS, registration gate, per-user YouTube connect, account
management, immediate web summarization, charmbracelet spinner,
auto/manual mode, public landing page) with the why and the
commit/ADR that covers each. Preserves the intent-vs-reality split.
Co-Authored-By: Claude Opus 4.8 (1M context) <noreply@anthropic.com>
The .feature spec lagged shipped behaviour. Added three files, no
duplication of existing scenarios:
- registration.feature: new Dex subject -> registration gate (users +
user_identities), returning subject straight through, account delete
is tapir-side only and leaves other users intact, clean
re-registration (ADR-012, ADR-013).
- summarize_mode.feature: auto summarizes every new video; manual
(default) leaves them unsummarized until queued; queued video is
processed and the flag cleared (migration 006).
- landing_page.feature: unauthenticated / -> /welcome, Get Started for
guests, summary link + logout for authed users, logout -> /welcome.
Scoped to built features only — no Vimeo/Whisper/billing scenarios.

The C4 view predated the web transport. Added a "Web surface" section
with a component diagram and prose covering: tapir serve (HTMX+Templ
over the unchanged store), oidc authenticate-only session, registration
gate (users + user_identities), per-user YouTube web connect callback,
account disconnect/delete (ADR-013 tapir-side only), immediate
summarization via background goroutine + HTMX status poll, and
auto/manual summarize mode (migration 006). Relabeled the L2 http node
to tapir serve. Corrected the out-of-scope isolation bullet: RLS is live
(ADR-012, migration 003), not deferred. ADR-003 stance preserved — the
engine/ports/sinks core is untouched; the web is a new transport.
Co-Authored-By: Claude Opus 4.8 (1M context) <noreply@anthropic.com>
The ER diagram and notes predated migrations 002-006. Brought them to
code truth:
- add summary_actions (002), user_identities (004), video_connections
(005) with real columns/constraints; rename token_secret_ref ->
token_ref to match migration 005.
- add users.auto_summarize and videos.summarize_requested (006).
- note FORCE RLS coverage and sink_deliveries' EXISTS-derived policy
(003); user_identities NOT RLS'd.
- mark AI_CREDENTIAL and SUBSCRIPTION as planned (no table exists; only
videos.subscription_id, no FK).

The "Isolation invariant" section said enforcement was dormant at
Stage 0. ADR-012 turned it on: Postgres RLS ENABLE+FORCE on every
user-owned table (migration 003_rls.up.sql), keyed off the
tapir.current_user_id GUC set by the store's withUser helper, deny-by-
default on an unset GUC. The Stage-2 two-user isolation test
(internal/adapters/store/rls_test.go) is pulled forward and passing.
Kept the ADR-011 single-user history honest.
Co-Authored-By: Claude Opus 4.8 (1M context) <noreply@anthropic.com>
The "Current build state" section described a scaffolded, intentionally
RED repo (ErrNotImplemented, go 1.23, unverified confirm items). All
stale: build is v0.4.0 green, go 1.26.1 (go.mod), Stage 1 multi-user
with RLS shipped (ADR-012, migrations 001-006). Rewrote to describe the
actual adapters, cmd subcommands (incl. serve), and how to build/run.
Replaced the "confirm" list with the resolved homelab facts (LiteLLM
koala:30401, model-as-config) now pinned in homelab-integration.md.

ADR-010 sat between ADR-008 and ADR-009. Moved ADR-009 (TBD) ahead of
ADR-010 (timedtext caption acquisition) so the file reads 001..014 in
numeric order. Pure structural move, no content change.
Co-Authored-By: Claude Opus 4.8 (1M context) <noreply@anthropic.com>
Package comment said "Stage-0 ... (ADR-011)" and User.Subject said
"single-user allowlist (ADR-011)". Both stale: ADR-012 opened Stage 1
(multi-user, RLS-enforced isolation). Subject is now the user_identities
lookup key (migration 004) resolving to a per-user UUID; an unknown
subject hits the registration gate.

Add a configurable fakeAuth (StubAuth can't express the logged-out case)
and assert: /welcome renders the logged-out CTA with no session and the
logged-in controls with one, unauthenticated / redirects to /welcome,
unauthenticated deep links redirect to /auth/login, and an authenticated
root still renders the list.
Co-Authored-By: Claude Opus 4.8 (1M context) <noreply@anthropic.com>
Wire GET /welcome on the root mux alongside /healthz, outside
Auth.Middleware. handleWelcome peeks the session via CurrentUser (no
redirect) and renders the logged-out or logged-in WelcomePage variant.

Add the public landing page: a static Charm-box tapir mascot (reusing the
shared tapirLine helpers and charm palette), a tagline, and a single
'Get Started' CTA into the shared Dex flow — sign-in and sign-up are the
same URL (ADR-012). Logged-in visitors get a greeting plus links back into
the app and to log out. Regenerated views_templ.go committed alongside.
Co-Authored-By: Claude Opus 4.8 (1M context) <noreply@anthropic.com>
Logout was bouncing the just-logged-out visitor straight back into a Dex
login. Land them on the public /welcome page instead — an intentional UX
fix. Cookie clearing and server-side session deletion are unchanged.
Co-Authored-By: Claude Opus 4.8 (1M context) <noreply@anthropic.com>
An unauthenticated visit to / now lands on the public /welcome page
instead of bouncing straight to Dex. Deeper guarded paths still redirect
to /auth/login so the post-login round-trip returns the visitor to the
page they asked for. isPublicPath runs first, so no redirect loop.
Co-Authored-By: Claude Opus 4.8 (1M context) <noreply@anthropic.com>
The landing page must render without a session. Add /welcome to
isPublicPath so the auth middleware lets it through (alongside /healthz
and /auth/*), and assert the bypass in the public-paths test.
Co-Authored-By: Claude Opus 4.8 (1M context) <noreply@anthropic.com>
Workstream A: public /welcome landing page (bubbletea aesthetic, one Dex login
flow, logged-in shortcuts) — with the oidc.go facts verified against main, incl.
the two corrections that only surface from reading the code (logout must redirect
to /welcome not /auth/login; bare-/ vs deep-link redirect split).
Workstream B: reconcile the guardrail docs against deployed reality (v0.4.0) —
auth.go comments, data-model isolation status + migrations 002-006 schema,
architecture web surface, use-case scenarios for the Stage-1 features, ADR
ordering, and a requirements-vs-shipped deviation check. Structured as two
parallel workstreams so the doc audit isn't done cursorily alongside the build.
ADR-013 records the deliberate choice that account deletion is Tapir-side only
(cascade + secret purge), leaving the shared Dex identity intact — clean
re-registration, but a noted GDPR-shaped gap if Future C ever arrives.
ADR-014 specifies timedtext 429 handling: Retry-After-aware backoff, a single
per-egress-IP rate gate shared by the batch and click paths, and honest in-flight
UX (summarizing / queued-waiting / no-transcript) so a rate-limited fetch never
presents as a stuck spinner or error. Whisper stays deferred pending measurement
of the sustainable rate, which this work finally makes measurable.
Replace the plain ASCII spinner with a Charmbracelet-style TUI panel rendered in
the browser: a dark terminal card holding a rounded purple box (╭─╮╰─╯│) around a
pink block-char tapir (▄▓▀█) with mint eyes (◕ ◕) and a snout that wiggles ∩→∪→~
across three cross-faded frames, plus a lipgloss-style progress bar whose mint
fill grows over a dim track via an 8s CSS clip animation.
Colours come from named palette consts (CharmPurple/Pink/Mint/Cream/Dim) applied
as inline span styles, so the box and CSS share one source of truth. Frames are
built by a small run/line helper that pads each row to a fixed interior width —
an internal test asserts every box row is the same cell width so the border stays
flush. Honours prefers-reduced-motion (static frame + partial bar).

Extract the engine wiring (YouTube source, AI-router summarizer, store sink)
into buildProcessor, shared by cmdRun and cmdServe. It returns (nil, nil) — not
an error — on incomplete config, which is the queue-only fallback for serve.
engineProcessor adapts the engine to web.Processor: load the video row, run the
engine, clear the manual queue flag on a produced summary (mirrors the runner).
cmdServe wires it onto web.App.Processor; cmdRun reuses buildProcessor so the
wiring is no longer duplicated.
Co-Authored-By: Claude Opus 4.8 (1M context) <noreply@anthropic.com>
Clicking "Summarize" now runs the summary in the background (when a Processor is
wired) instead of only queuing it. The handler flips the DB flag, kicks off the
work on a detached context, and returns an animated "processing" card that polls
GET /v/{id}/status every 2s via HTMX. Status returns the summary card once it
lands (no poll → polling stops), the animation while in-flight, or the Queued
card otherwise. Queue-only behaviour is unchanged when no Processor is set.
The spinner is a CSS-only cross-fade of three ASCII tapir frames — no JS, honours
prefers-reduced-motion.
Co-Authored-By: Claude Opus 4.8 (1M context) <noreply@anthropic.com>
Add the seam for immediate web-triggered summarization. Processor is the
optional single-video summarize port (nil = queue-only, unchanged behaviour);
ProcessingSet is an ephemeral, concurrency-safe set of in-flight (user,video)
ids so a status endpoint can show progress until the summary lands. State is
deliberately in-memory only — the DB holds the durable truth across restarts.
Co-Authored-By: Claude Opus 4.8 (1M context) <noreply@anthropic.com>
The list now shows ALL videos (ListVideos), not just summaries. Summarized cards
are unchanged; discovered-but-unsummarized videos render with a muted "pending"
treatment and either a "Summarize" button or a "Queued" chip.
- POST /v/{videoId}/summarize queues a video (RequestSummarize) and returns the
refreshed card — it does NOT run the engine inline; `tapir run` is the single
summarization driver, which picks up the flag on its next pass.
- Account page gains an Automatic/Manual toggle (POST /account/summarize-mode →
SetAutoSummarize), shown as the current mode with a one-click switch.
- Both new POSTs degrade without JS (redirect back); HTMX swaps the fragment.
VideoCard and summarizeModeControl are extracted templ fragments reused as the
HTMX swap targets. views_templ.go regenerated.
Co-Authored-By: Claude Opus 4.8 (1M context) <noreply@anthropic.com>
RunOnce now reads the user's mode (GetAutoSummarize) at the start of each pass:
- Auto (unchanged): summarize every unseen video.
- Manual: still UpsertVideo for every candidate (discovery — the user sees new
videos in the list), but skip ProcessNewVideo unless the video is queued
(RequestedVideoIDs). A queued video is summarized, then its flag is cleared
(ClearSummarizeRequested) so it is not re-processed and the UI drops "Queued".
New Stats.SkippedManual counts discovered-but-unqueued videos. The VideoStore
port gains the three methods; the existing auto-mode tests set auto:true.
Co-Authored-By: Claude Opus 4.8 (1M context) <noreply@anthropic.com>
Add the store surface for summarization mode:
- SetAutoSummarize / GetAutoSummarize — per-user auto/manual toggle; an absent
user reads as manual (the safe default).
- RequestSummarize — queue one video (summarize_requested=TRUE); ErrNotFound
when the video is absent or not owned (RLS hides another user's row).
- RequestedVideoIDs / ClearSummarizeRequested — the run-loop side: load the
queued set per pass (mirrors SeenVideoIDs), clear after summarizing.
- ListVideos / GetVideoRow — drive from the videos table LEFT JOIN summaries so
discovered-but-unsummarized videos appear with empty summary fields. SummaryRow
gains additive Summarized + SummarizeRequested fields; the summary-only reads
are untouched.
RLS proof: rls_test.go gains a cross-user "queue B's video" write asserting it
touches zero rows (store-level scoping can't prove this — the test pool is a
superuser that bypasses RLS, same caveat documented there).
Co-Authored-By: Claude Opus 4.8 (1M context) <noreply@anthropic.com>
Add the schema for the summarization-mode feature: a per-user auto/manual
toggle (users.auto_summarize, default FALSE = manual) and a per-video manual
queue flag (videos.summarize_requested, default FALSE).
Both columns land on tables that already have ENABLE + FORCE ROW LEVEL
SECURITY (migration 003), so they inherit per-user isolation automatically —
no policy changes needed. auto_summarize is per-user, not global, per ADR-012.

GET /account shows the registered display name, the signed-in email, the
user's connected video accounts (status + when), a Connect-YouTube link
when none is connected, and the disconnect / delete controls. Linked from
the header nav.
POST /account/disconnect/{provider}: deletes the OAuth token from the
SecretStore (resolved from the connection's own token_ref, provider-
agnostic) and the connection row. Does NOT delete the account.
POST /account/delete: confirm-before-destroy (a <details> disclosure gates
the destructive submit — works without JS). Captures token refs, calls
store.DeleteUser (cascades all rows), purges every secret, then routes to
/auth/logout to clear the session. Tapir-side only — Dex is left untouched
(decision 2026-06-03).
Account handlers depend on a narrow SecretRemover (Delete) and the extended
Store port; cmd/tapir serve shares one file-backed SecretStore between the
connect flow and account management.
Tests: account page renders connections + name + Connect link; disconnect
removes token (fake records Delete) + row and keeps the account; delete
wipes users/summaries/connections/identities and purges the token, then
redirects to logout.

Add a one-shot flash component used across the app — connect success,
disconnect, account delete, and registration — instead of per-page ad-hoc
markup. setFlash queues a short-lived HttpOnly+SameSite cookie carrying an
opaque code; takeFlash consumes it on the next full-page render (not on
HTMX fragments). flashBanner maps the code to a styled, role=status banner;
the message text lives server-side in flashMessages so the cookie never
carries free text and a forged/unknown code renders nothing.
Wire it into the list page (the PRG landing spot for connect/registration)
and set it on registration and connect-callback success. Styled with the
existing design-system tokens; header gains an Account nav link.
Co-Authored-By: Claude Opus 4.8 (1M context) <noreply@anthropic.com>
Account disconnect/delete needs to remove the per-user YouTube refresh
token from the SecretStore. Add Delete(ref) on the file-backed store,
mirroring Put: atomic temp-file+rename, 0600, no-op on an absent ref.
Kept off the read-only ports.SecretStore (Get) — write/delete follow the
existing auth.TokenWriter convention of narrow capability interfaces, so
the youtube adapter's read-only dependency is unaffected.
Co-Authored-By: Claude Opus 4.8 (1M context) <noreply@anthropic.com>
DeleteUser permanently removes a user and all owned data, scoped via
withUser. The users-row ON DELETE CASCADE reaches videos, transcripts,
summaries → sink_deliveries, video_connections, and the user_identities
map (cascades bypass RLS, so a scoped connection still wipes child rows).
summary_actions carries user_id but has NO FK to users (migration 002),
so it is deleted explicitly in the same scoped transaction. Idempotent.
Tapir-side only (decision 2026-06-03): Dex identity is left untouched;
secrets live in the SecretStore and are removed by the account handler.
DisplayName returns the registered name for the account page.
Test proves deletion removes every row for the target user across all
isolated tables (incl. video_connections AND user_identities) and leaves
another user's rows fully intact.

Add GET /oauth/youtube/connect and /oauth/youtube/callback, mounted inside
the login + registration guard so CurrentUserID is always set and every
connection binds to the authenticated tapir user.
- connect: generate a per-user CSRF state (single-use, short TTL, bound to
the user), redirect to Google consent with access_type=offline and
prompt=consent so a refresh token comes back.
- callback: verify the state belongs to this user, exchange the code via the
existing auth.Exchange, persist the refresh token under a PER-USER ref
(web.YouTubeTokenRef = "youtube/<userID>/refresh_token") so tenants never
collide, then UpsertConnection (provider=youtube, status=active). Any
failure renders a clean error page and leaves no half-written state.
Reuses auth.Exchange and adds auth.AuthCodeURL (offline + consent) rather
than the CLI's listener/terminal flow (ADR-006: web flow, not CLI). The
ConnectHandler depends on a narrow web.Connections port, not the concrete
store. Wired in cmdServe only when YT client credentials are present;
TAPIR_YT_CONNECT_REDIRECT_URL configures the callback URL. Per-user token-ref
scheme documented in docs/homelab-integration.md.
